Inspection & Integrity Management

Off Shore | Pipe Line | Certification| Verification
Welding Inspection & Qualification

Off shore

Corrosion surveys for classification societies such as Lloyds Register, ABS Pacific and DNV.

Ultrasonic thickness surveys on process pipe work and process vessels utilising A and B Scan methods as well as Time of Flight Diffraction (TOFD).

Radiographic inspection on process pipe work and process vessels: this includes the use of Small Confined Area Radiography (SCAR) technology. This technology allows radiographic testing to be carried out with a barrier diameter of 3 -5 metres.

In the offshore environment where space is at a premium this simple method can provide huge savings in preventing down time in work to allow conventional radiography to take place. 

DITS can provide qualified coating inspectors to carry out coating condition surveys or provide third party assessment of coating and abrasive blasting contractors.

Pipe line

DITS works closely with a major overseas based inspection company Oceaneering to carry out offshore and onshore inspection of pipelines, by the use of internal and external X-ray crawlers.

Certification / In-service Inspection

Hydrostatic Pressure Testing:

DITS are a NATA accredited laboratory and are capable of carrying out Hydrostatic Pressure testing on process pipe spools and pressure plant up to 120,000 KPa.  Testing can either be carried out onsite or at a DITS base.


Third Party and Vendor Inspection:

DITS can supply inspectors to carry out third party verification and auditing on behalf of Clients.

Typically servicing the Oil Gas and Mining Industry for Companies such as PTTEP Australasia (Ashmore Cartier) Pty Ltd, Clough Amec JV and Conoco Phillips through our extensive client base.
